When I stopped to think about your question, it could be easy to think soil and sand "grows". But it does not grow. Instead, sand accumulates in different areas.

Sand is tiny grains of rock. Rain, freezing temperatures that create ice inside tiny cracks, and wind begin to break up big rocks until they become smaller and smaller, and eventually so small that it is called sand. Water and Wind then move sand to different places, even long distances away.

Oceans, lakes, rivers, streams, and creeks all carry grains of sediments, including sand. These waterways carried (and still carry) sediments from the Appalachian Mts in Pennsylvania, all the way to the Rocky Mountains in Colorado. This movement goes on all across the world, wherever there is moving water. As well, oceans bring sand from the ocean floor and pushes it onto land with each wave.

The winds across the world pick up the tiniest grains and move the particles across the globe.

In western US and Middle Eastern Countries, sand-wind storms can suddenly blow across the land, moving grains of sand and soil to new places.

In places where the sand piles up without strong winds to blow it around, mounds called sand dunes form. But ocean waves especially during storms, or winds in the desert, can quickly remove a big mound of sand without much trouble. The ocean waves draw sand back into the ocean. Winds on land during storms mostly spread sand around, often carrying it long distances, even across the oceans.
